At the Screen Actor Guild Awards, the "30 Rock" star revealed that a former girlfriend, Tanisha, came to the rescue when he needed the organ transplant in December. It is unclear if they were together at the time of the donation.

"I'd like to thank Tanisha for donating my kidney to me," Morgan told E!'s Giuliana Rancic on the red carpet.

The "30 Rock" star underwent a kidney transplant on or around Dec. 10, which led him to miss filming at least two of the show's episodes set to air in March, EW.com reported last month. But Morgan, who also suffers from diabetes, has recovered from the surgery and looked as healthy as ever on the red carpet Sunday night.

"We were together, but then we separated," Morgan said. "But she also gave me a kidney."
